Have you ever run out of disk space, and then wondered where all the big
files were that you needed to delete? In Windows you have the fun
task of right-clicking on every directory to get its size, and then
repeating the procedure on all its subdirectories. On Unix, you
end up doing `du -csh *` or
`du -cs | sort -n` in every
directory. This program simply displays a directory tree sorted by size
and lets you mark files and directories to delete. This way all your
big directories are at the top, and easy to find.
